Patent CA-2022199-A1 (CA)
Title: Automatic trap drag
Inventor: WADDINGTON STANLEY
IPC: A01M23/00
Filed: 1990-07-30
Abstract: STANLEY WADDINGTON APPLICATION FOR PATENT FUR BEARING ANIMALS TRAP DRAG          ABSTRACT This invention is intended to prevent trapped animals  from  running away with a trap.  It is somewhat similar to the solid three prong fur bearing animal trap drag.  The difference and real improvement of this drag  over  the solid  three  prong  drag  is that when the drag is set, it lays very close or flat to the ground(approximately 3 inches off the ground) and  can  be  easily hidden or covered with grass. The drag appears to be similar to a three  prong  anchor except  the third  prong  is spring loaded and can be moved to the side next to one of the other prong  and held in place by a pin.  This allows the drag to lie flat and be  unnoticed.  The pin is attached to the trap by a chain.  When an animal is caught in the trap, it tends to attempt to run away, this  movement to  escape will release the pin holding the third prong thus making it almost a certainty the drag will get caught on a tree  or underbrush and hold the animal in place for the trapper. The drag is very compact thus making it much easier for the  trapper to  transport.   The  pin  is  removable, thus making it easier to replace the spring should it happen to break rather than replacing the complete drag.

Inventor: GYULAI PETER
IPC: C02F1/58
Filed: 1990-10-02
Abstract: HYDROGEN PEROXIDE DESTROYING    COMPOSITIONS AND METHODS      OF USING SAME            ABSTRACT OF DISCLOSURE           A composition and method useful  for destroying hydrogen peroxide in a liquid aqueous medium, such as that used  to  disinfect  contact  lenses,  are  disclosed.    The composition  comprises  at  least  one  hydrogen  peroxide destroying component effective when released into a liquid aqueous medium to destroy or cause the destruction of hydrogen peroxide present in the liquid aqueous medium, and a barrier component acting to substantially prevent the release of the hydrogen peroxide destroying component for a period of time after the composition is initially contacted with a hydrogen peroxide-containing  liquid  aqueous  medium.    The  barrier component  includes  a water  soluble  portion  and  a  water insoluble portion. The hydrogen peroxide destroying component is situated so as to be released into the hydrogen peroxide-containing liquid aqueous medium in response to the dissolving of the water soluble portion into the hydrogen peroxide-containing liquid aqueous medium.

Filed: 1990-10-03
Abstract: Abstract of the Disclosure A robotic apparatus for positioning a tool or work hand that incorporates a compliant wrist effective to adjust to delicate but misaligned portions of the workpiece, comprising (a) means for magnetically supporting a positioning member carrying a gripper tool; (b) pneumatic means for selectively separating and floating the positioning member from said supporting means to permit lateral adjustment of the positioning member in response to small forces received from the gripper tool as it carries out gripping; and (c) means for locking the positioning member to the supporting means upon completion of the desired lateral adjustment.          A  method of using such compliant wrist concept, comprising (a) magnetically suspending a positioning plate from a magnet, the plate carrying the gripper tool; (b) injecting a film of air between the interface of the magnet and plate to provide floating separation therebetween enabling ease of lateral movement; (c) closing a gripper tool about the part to be gripped causing any offcenter gripping forces to be translated back to the plate resulting in lateral movement in response thereto for seeking a centering position; and (d) upon achieving the desired centering position, deactivating the air injection to permit the magnet to lock the plate in position relative to the magnet for further robotic movement.

Title: Process for applying ceramic coating using a plasma jet carrying a free form non-metallic element
Inventor: HENNE RUDOLF
IPC: C23C4/137
Filed: 1990-04-26
Abstract: Process for applying a coating of ceramic material on a substrate by plasma spraying.  The material to be sprayed, which is incorporated in the plasma jet, includes a chemical compound one constituent of which is a nonmetallic element from the group N, C, B or from main groups VI or VII of the periodic classification, which decomposes, at least partially, in an inert environment before reaching the melting point and which is present in the solid phase in the applied state.  To improve the process so that the chemical compound contained in the material can be applied to the substrate stiochiometrically, i.e., undecomposed, and form an impermeable, adherent, stable coating, the non-metallic element is incorporated in the plasma jet, in addition to the material to be sprayed, in a free form, not bound to a foreign element.

Title: Pressure limiting valve with stepped or double piston
Inventor: VOSS RICHARD
IPC: F16K17/04
Filed: 1990-05-10
Abstract: (57) Abstract The feature of a pressure limiting valve with flow rates of 3000 litres per minute and more is a cylindrical piston (10) ar-d to slide longitudinally in the valve casing (2) against the force of a spring (11).  The valve (1) is divided into two chambers (46, 47).  With the attached control piston (60), the valve piston (10) forms a structural unit in which the control piston with its correspondingly smaller diameter is loaded via the spring cap (26) and the valve spring (11).  The valve spring (11) is adjustable so that the opening point of the pressure limiting valve (1) may be preset.  The special design of the stepped valve piston (10) with the control piston (60) makes it possible to use relatively weak and small valve springs (11), thus making the entire valve compact. The response of the pressure limiting valve is ensured owing to the stepped design of the valve piston (10)/control piston (60) and the sealing rings (19, 51) used, which are fitted on the outside of the large diameter valve piston (10) without perceptibly hamper-ing its movement through friction.  Sealing is nevertheless ensured because the sealing rings (19, 51 and 75) used are very hard and create little friction.

Abstract: APPARATUS FOR EXTRACTING LIQUID FROM A COMPOSITE MASS  ABSTRACT OF THE DISCLOSURE         An apparatus for removing liquid from a composite mixture of liquid and solids comprising a hopper 16 mounted atop a compactor ram assembly 10, having a snout section 12 and an extruder section 14 mounted in a generally axial direction to the compactor ram assembly 10.  Wet waste material is loaded into the hopper 16 and falls onto a loading floor 158.  A hydraulically operated ram 208 compresses the wet material into the snout and extruder sections 12, 14.  Under pressure from the ram 208, liquid in the waste material escapes from numerous drainage holes 25 in the loading floor, the snout section top, bottom and sides 24, 22, 20, the extruder section top, bottom and sides 30, 28, 26 and holes 212 in the ram face 210.  A platen 80, pivotally mounted to the extruder top plate 30 near the exit of the device and biased with a constant pressure, controls the back pressure in the extruder and snout sections 14, 12.  A first embodiment has a converging extruder section 14, having a narrower cross section at the exit of the section, which aids in compacting the material being dewatered.  A second embodiment has a slightly diverging extruder section to prevent impaction of dewater material inside the device when operating with certain composite mixtures such as paper pulp.
